WHEEL FOR VALVES AND THE LIKE.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed May 24, 1916. Serial No. 99,651.

To all whom it may concern:

Be it known that I, JAMES P. WALL, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Wheels for Valves and the like, of which the following is a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in which Figure 1 is a plan view partly broken away of a completed hand wheel embodying my invention;

Fig. 2 is a section on the line 11-11 of Fig. 1;

Fig. 3 is a side view showing the grip member partially formed; and

Fig. 4 is a sectional view of the partially completed wheel.

My invention has relation to hand wheels or handles for valve stems and the like, and more articularly, to devices of this character in which the hand grip is formed by a helix of wire seated upon a central member or core.

The object of the present invention is to provide means of simple, novel and eflicient character for securing the hand grip upon the central member or core.

In accordance with my invention, I provide a central member or core 2, consisting of a hub portion perforated at 3, to receive the valve stem or spindle, and a rim portion. This member 2 is formed of brass, copper, or other malleable metal which can be bent or flanged, and is initially provided with the outwardly bent flange 4; at one end, the other end being left substantially unflanged. 5 designates a coil or helix of wire, and 6 an annular attaching band. In the manufacture of the hand grip, the coil or. helix 5, which has been opt to the proper length, is threaded upon the annular band 6 in the manner indicated in Fig. 3. After the helix has been threaded upon the band 6 in this manner, it is slipped on to the straight end of the member 2, which it preferably fits snugly, and this end portion of the member 2 is then flanged outwardly, as indicated at 7 in Fig. 2. This causes the hand grip to be securely pinched between the two flanges 4. and 7, so as to prevent its rotating upon the member 2. This forms a very simple, secure,

and effective method of attaching the hand grip.

I claim:

1. A device of the character described, comprising a central member or core having a recessed rim portion, a helical wire hand grip seated in said recess, and a separate band or annulus within said helical wire for holding it in position in the recess; substantially as described.

2. A device of the character described, comprising a central member having two flanges on the periphery thereof, a coiled wire hand grip seated between the flanges, and means within the hand grip engaging the different coils of the hand grip, said coils being frictionally clamped in position between said means and the said flanges; substantially as described.

3. A device of the character described, comprising a central member or core having a double flanged rim portion, there being an annular space between said flanges, a coiled wire hand-grip seated in said recess, and an annulus within the coils of the hand grip, said hand-grip being secured therein by being compressed between the flanges and the annulus; substantially as described.

4. A device of the character described, comprising a central body member having a concave rim portion, a hand grip seated on said rim portion and consisting of a wire helix, and a clamping member engaging the individual turns of the helix and clamping each of them against pivotal movement on their points of contact with the rim, sub stantially as described.

5. A device of the character described, comprising a central body member having a concave rim portion, a hand grip seated on said rim portion and consisting of a wire helix, and a clamping member engaging the individual turns of the helix, said clamping member and rim having a forced clamping engagement with each other, substantially as described.

In testimony whereof, I have hereunto set my hand.

JAMES P. WALL.
